Defrost control method in a refrigeration installation and associated control device

A method to manage defrosting of a refrigeration plant provided with at least one compressor and at least one evaporator, the method comprising:

• defining a plurality of defrosting modes, which can be selected by the end user in a non-exclusive manner, which are based on one or more functioning parameters of the refrigeration plant, said functioning parameters being detected by means of detection probes provided in the refrigeration plant comprising at least one of pressure switches, thermostats, and timing devices associated with said compressor and/or said evaporator;
• and
• memorizing said plurality of defrosting modes in an electronic device to manage the defrosting, said electronic device being configured by the end user through means able to select said plurality of defrosting modes, in which the functioning parameters of the refrigeration plant are selected and adjustable by the end user for each of the defrosting modes memorized in the electronic device, such that said defrosting modes are activated individually or in a modular manner.
